Toughbuilt Insulation Knife – Heavy-duty Sheath with Belt Clip – 6†Titanium Coated Stainless Steel Blade – TB-H4S-40-IK-2

Excellent insulation knife. This is my third insulation knife and by far the best brand I have purchased. Pretty sharp out of the box, the sheath is secure, and the handle feels really nice in the hand.

Cuts batts like butter, dull when you get it but put a small edge on it and it's amazing. It's an insulation knife and works for that probably not the best utility knife out there like some comments say but the word insulation is in the title so I don't feel like you can get mad when that's all it cuts. I use mine on batts and 10 mill plastic when prepping works great to that end 10/10 would and will buy again when time comes

Awesome. I would like to buy again, but not available. A must for cutting at work site.

Satisfied with product, dissatisfied with delivery. Package was ripped open.

I gave it a 5 star review because it did cut insulation very nicely however it didn't do anything else well. I'm not going to carry a knife just for insulation, you're much better of with the Milwaukee duct knife that is more universal
